Spencer Pratt is known to speak his mind, but recently he has seemed to cool down and just been enjoying spending time with his wife Heidi Montag.

However, good things can't last for too long!  In a recent interview Pratt slammed another reality star, Kim Kardashian, saying that her image is not good for the media any longer!

"Kim has totally lost the plot.  She should have kept up her good girl act and image," Spencer said in an interview with FOX411.  His comments stem from Kim's racy Super Bowl commercial and the naked magazine covers she has recently been 'complaining' about.

"She had better be careful.  The people who buy her products aren't guys, they're girls, and girls don't want to see Kim naked during the Super Bowl," Pratt continued.

Spencer, of course, had some advice for Kim, too.

"She should just disappear," he advised.  "[Heidi and I] saw the public reaction when we were overexposed and we took ourselves out of the equation.  Kim needs to do that before she puts the nail in her coffin."

OUCH!! Unfortunately for Spencer, it doesn't seem like Kim or any of the other Kardashian sisters will be going anywhere anytime soon.  With four reality television shows between them, stores in New York, California and Miami and more endorsement deals than they can probably handle - the Kardashians look like they'll be sticking around for a while!
